Care
Chromis xanthura is a hardy species that is well-suited for both novice and experienced aquarists. They thrive in well-established aquariums with plenty of swimming space and rockwork for hiding. They are omnivorous and will accept a variety of foods, including frozen and flake foods, but a diet rich in marine-based proteins and vitamins will promote their health and coloration.
Reproduction
Like many damselfishes, Chromis xanthura can breed in captivity. They are oviparous, with females laying eggs on a flat surface, which are then fertilized by the male. The male guards the eggs until they hatch, which typically occurs within a week. Raising the fry can be challenging and requires a separate rearing tank with appropriate food, such as rotifers and baby brine shrimp.
Habitat
The Yellowtail Damselfish is native to the Indo-Pacific region, where it is commonly found in coral reefs and lagoons. They prefer areas with strong water movement and can often be seen in groups, darting among the corals and rocks.
